--- Quote Start --- I would double check your board design, top-level FPGA design connections and the connections from that top-level to SOPC Builder, first. - Use the Altera kits that include the 91c111 as a guide. - Pay attention to _all_ signals, not just the ones that are connected to the SOPC Builder module! Then I would proceed to stepping through the initialization of the ethernet driver in alt_sys_init.c (built as a part of your System Library...or BSP, depending on the flow you use). Cheers and Good Luck! - slacker[/b] --- Quote End --- Thanks slacker, it succeeds, looking at other example design I found that resetn_to_lan91c111 from SOPC module wasn't really connected to the lan91c111 reset pin, along with other pins that are tied to a fixed voltage (VDD or VSS) on the board by some resistors. Now everything seems to work, I can, at least, connect to the socket. Thanks alot for your collaboration. Kind regards. Massimo
